Library with Python models derived from the page package world.opensemantic.quantities

opensemantic.quantities

Pydantic models for physical quantities, units and prefixes from world.opensemantic.quantities.

Provides typed Python classes for working with units of measure, unit prefixes, composed units, and quantity kinds based on the QUDT ontology. Includes SI, CGS, and commonly used non-SI units (bar, atm, calorie, etc.).

Installation

pip install opensemantic.quantities

Usage

from opensemantic.quantities import QuantityUnit, ComposedUnit, UnitPrefix, QuantityKind

# Pydantic v1 models
from opensemantic.quantities.v1 import QuantityUnit as QuantityUnitV1

Models

Class	Description
UnitPrefix	SI unit prefixes (kilo, milli, micro, etc.)
QuantityUnit	Base units with prefix variants (metre, second, pascal, bar, etc.)
ComposedUnit	Units composed of multiple factors (m/s, kg*m/s^2, etc.)
QuantityKind	Physical quantities (Length, Mass, Pressure, etc.)
PrefixUnit	Prefixed variant of a unit (subobject of QuantityUnit)
ComposedUnitElement	Prefixed variant of a composed unit (subobject of ComposedUnit)

Dependencies

• opensemantic.core - base entity models (Entity, Item, Label, etc.)
